i have a cabinet 0.8mdeep 1m wide 2m high in feet its 2.6246719x3.280839895x6.56167979 i use a 400 sonagro hps with blue spectrum added in a cool tube. i use a 175m3/h 6180.066ft3/h inline duct fan the air flows in the from a 12,5cm/4.921inches duct that hangs from the sealing down to the cool tube on the other side of the cooltube the ducting that leads to the inline RVK UFO fan a duct from there to my carbon filter that is placed in a sealed box with a 10cm/3.937inches hole on the other side that leads all the air out the hole on the back of the cabinet. the fan im using also has a 10 cm in/output. my temps range from 19c to26.5c/66.2f to 79.7f. i have a cheap humidifier, have added cups with water but cant seem to stabilize the humiity. as long as the humidifier is on i get my humidity up to 38%max and then it drops when the water in the tank is over about 10/12hours later the humidity almost instantly drops under 10%. i have 2 air intakes at the bottom 10cm each one with a computer fan the other passive. any help to raise humidity higher as around 55% without adding another humidifier. also i think we could try and raise the huidity in the outer room where the air flows from so any ideas on that are welcome 2!!!!:bigjoint:

you could get a 5 gallon bucket, at pong fogger and that should raise humidity, being that it is 5 gallons it should last a couple days if not more

isnt it good to find the info you want on your own?? simple logic manytimes will suffice!! my humidity is constantly around 60% so i guess i found the way!!! first thing i did as strange as it may seem was to remove 1 oscillating fan that mixed the hot air from top part of cabinet with low(cool) air from bottom and this besides temperature increases also didnt allow for humidity to build!! then i have some water bottles as i used bottled water for watering and just unscrewed the lid and left them open in addition i place water in one of my empty guano plastic containers and have left it in the room under the light as i saw this gave humidity i added a plastic blue pan like in the room with 3cm of water in it and thats the trick!! ow i also am growing some basil and thyme for my girls cooking and i simply water them more often as they too release humidity in my room!! hope this helps anyone else!! by the way i have totally removed the humidifier as it got temps up and was too much of a hassle!!!

Why would you want the humidity that high - unless it's for seedlings or clones?
